WASHINGTON — Director of National Intelligence Sarah Mitchell is under investigation by the House Intelligence Committee following accusations that her agency altered congressional briefings on Iran's nuclear program to match administration talking points.

Democratic committee members allege that classified intelligence reports presented to Congress in February omitted key findings about Iran's uranium enrichment activities. The disputed intelligence reportedly suggests Tehran's weapons development timeline differs significantly from public statements made by administration officials. "We have evidence that critical assessments were removed from briefings to support predetermined policy positions," said Representative Michael Chen, the committee's ranking Democrat.

The controversy centers on intelligence gathered by the CIA and Defense Intelligence Agency regarding Iran's centrifuge operations at the Fordow facility. Sources familiar with the classified materials indicate the original assessments contained technical data showing slower progress in weapons-grade uranium production than publicly claimed. Former CIA analyst Rebecca Torres told The Meridian that selective intelligence presentation "undermines the entire purpose of independent analysis."

Mitchell's office denied the allegations in a statement Tuesday, calling them "politically motivated attacks on professional intelligence officers." The DNI emphasized that all congressional briefings follow established protocols for protecting sources and methods. However, three Republican senators have now joined calls for the Intelligence Community Inspector General to review the briefing materials, suggesting bipartisan concern about intelligence politicization.
